How to Prevent Web & App Data Tracking on Your iPhone in iOS 15

* This article is from our Tip of the Day newsletter. . *

This activity data is often sold to third parties to help them make advertising decisions. With iOS 15, they can’t track your data on the iPhone without your permission, but sometimes it’s easier to just stop apps from asking in the first place. We'll show you how.
